我试图在R中将大数字转换为十六进制表示,但它失败了,因为它不能适应32位整数。有没有办法克服这个限制?
> print(0xffffffff+0x10000000)
[1] 4563402751
> as.hexmode(0xffffffff+0x10000000)
Error in if (is.double(x) && (x == as.integer(x))) x <- as.integer(x) :
missing value where TRUE/FALSE needed
In addition: Warning message:
In as.hexmode(4294967295 + 268435456) : NAs introduced by coercion
答案 0 :(得分:3)
幸运的是我找到了解决方案,但需要库gmp
library(gmp)
> as.character(as.bigz(0xffffffff+0x10000000),b=16)
[1] "10fffffff"
